Type E TO2
Type E TO2 is an electronic controller for fully automatic,
economical ice and s now melting on outdoor areas and in
gutters . Ice forms due to a combination of low
temperature and mois ture. E TO2 detects both
temperature and mois ture, and the s now melting s ys tem
will us ually only be activated if s now or ice is pres ent.
E TO2 is s uitable for controlling electric heating cables , or
water-bas ed heating pipes .

SENSOR INSTALLATION
Ground sensor ETOG, fig. 1+3:
For installation on outdoor areas where snow and ice is a
regular problem. The sensor must be embedded
horizontally with its top flush with the surroundings. Use
the accompanying installation plate.
The sensor cable must be installed in accordance with
current regulations. We recommend that cable pipes be
laid to protect the sensor cable. Detailed installation
instructions are supplied with the sensor.
Gutter sensor ETOR, fig. 2+4:
For installation in a gutter, or downpipe on the sunny side
of the building. It is important to ensure that the sensor
contact elements face against the flow of melt water. If
necessary, two sensors can be installed in parallel.
Detailed installation instructions are supplied with the
sensor.
Note that the pink and grey wires are not used.
ETO2
Outdoor sensor ETF-744/99, fig. 2+4:
ETF is for use with gutter sensor ETOR. ETF can also be
used separately for the detection of temperature alone.
The sensor should be mounted on the wall beneath the
eaves on the north side of the building.
Water sensor type ETF-1899A:
Only for use in waterbased system to detect temperature
in supply and return water. Must be fastened with strips
fixed directly on the pipe.
Sensor cables:
ETOG and ETOR are supplied with 10 m cable, which can
be extended up to approx. 200 m using standard
installation cable: 6x1.5 mm² for ETOG and 4x1.5 mm² for
ETOR. The ETF cable can be up to approx. 50 m in length.
Sensor cables must be installed in accordance with current
regulations. They must never be installed parallel to power
cables as electrical interference may distort the sensor
signal.
ETO2 installation
The unit is intended to be DIN-rail mounted in an
approved panel.
Wall mounting:
English
For USA and Canada: The thermostat can be wallmounted in a specially designed and UL-approved metal
box (accessory).
For other countries: The accompanying plastic cover can
be used for wall mounting in an indoor area.

(normally open).
Connect external standby button to terminals 33-34.
Connect external forced heat button to terminals 35-36.
English
TESTING SNOW MELTING SYSTEM
After completing installation and application setup, it is
recommended that the snow melting system be tested.
1. Adjust SET TEMP in the setup menu to max.
temperature.
2. Pour some water onto the sensor (ETOG/ETOR).
3. The output relay for the heating cable in the zone
concerned should activate and ON should be
indicated on the ETO2 display. Check that the
heating cable becomes warm, check the voltage if
possible.
4. After testing, adjust SET TEMP back to the desired
setting (factory setting = +3.0°C / 37.4°F).
